One ticker. Three answers.

Instead of pulling data from five different websites, Holygrail AI runs the full analysis and shows you where every number comes from.

Fair value

Several valuation models, chosen and weighted according to the type of company: mature, cyclical, growth or bank.

DCFPeer multiplesDividends

Financial health

Whether the balance sheet holds up, whether profits turn into cash and how high the bankruptcy risk is.

How it works

Type the ticker

NVIDIA, AMD, ASML or any other listed company. The app fetches market data and financial statements.

The app picks the models

A mature company, a bank and a REIT are not valued the same way. Holygrail AI uses the right models for each case.

Understand every number

Every calculation is explained. In advanced mode you adjust growth, tax and margin of safety and run it again.
